Abstract (en)
[origin: WO2007148284A2] The invention relates to a method (1) for determining a threshold in an image comprising image values, said method comprising the steps of: analyzing (3) the image values for determining edge points and associated gradients; classifying (5) image values into classes with respect to the edge points; obtaining (7) image threshold by combining data from the intensity histograms calculated for each class with statistical analysis of the said histograms. The invention further relates to a method of image segmentation, an image processing system and a computer program.
